基于热固性聚合物基体的导电纳米复合材料（NC）由于其独特的性能组合和广泛的应用而引起了科学界的广泛关注。特别地，导电NC代表了一类特殊的结构坚固的混合材料，其可以扩展用于减轻静电荷或用于提供针对电磁干扰（EMI）的屏蔽的有吸引力的解决方案。本章从EMI屏蔽的基本介绍、理论表达式和测量屏蔽效能的实验技术开始。在下一节中，将全面介绍热固性NC的电气和EMI屏蔽性能，特别是基于导电添加剂（如本征导电聚合物）和碳质填料（如碳纳米管和石墨烯）的性能。最后，展望了纳米碳的加工和应用前景。
Conducting nanocomposites (NCs) based on thermosetting polymer matrices have attracted considerable scientific attention in the recent past due to unique combination of properties and wealth of prevalent applications. In particular, electrically conducting NCs represent a special class of structurally strong hybrid materials that can extend an attractive solution for mitigation of static charges or for providing shielding against electromagnetic interference (EMI). This chapter begins with the basic introduction of EMI shielding, theoretical expressions, and experimental techniques for measurement of shielding effectiveness. In the next section, a comprehensive account of electrical and EMI shielding properties of thermosetting NCs is covered with special reference to those based on conducting additives like intrinsically conducting polymers and carbonaceous fillers like carbon nanotubes and graphene. Finally, prospects and challenges associated with the processing and applications of these NCs are discussed.
